I have a question about pressing dry ice hash. Isn't (small micron) dry ice hash just trichome heads, i.e. basically pure THC? And isn't rosin an attempt to arrive at the same product?
What is the advantage of pressing hash? And what's the puck made of when you're done?
Okay, a few questions.
1. Isn't (small micron) dry ice hash just trichome heads, i.e. basically pure THC? In a perfect world, yes. However, I don’t care how small the hole is, particulate shit will always find a way in the pile. Especially with dry ice. The dry ice and agitation causes heads, stems, green shit, and everything to be pulverized (my theory) so some fall threw the screen. Everyone wants the best quality so squishing it, with smaller micron bags, gives a better product...in theory.
2. And isn't rosin an attempt to arrive at the same product? Good question. Rosin has a plethora of stuff (in scientific terms) in it, ie. waxes, lipids, microscopic particulates, etc., not just cannabinoids, terpines, thc, cbd, etc. The heat and pressure just releases it all. Bubble hash gives a better product because you can actually separate heads from stems, less particles, etc. I have seen some mediocre bubble hash squished into some fire rosin. Although I sampled it, I didn’t do the work. I think, but not sure, that butane or CO2 dissolves much of the wax, etc. leaving a cleaner product also.
3. What is the advantage of pressing hash? Better product is the goal.
4. And what's the puck made of when you're done? Smashed hash. It looks like the old hash you got back in the day, but flat and dry. It crumbles, but I’m sure there’s still something good in there. I threw them in my puck jar that lives in the freezer...for later alcohol extraction.
Those are my guesses. I don’t know the exact science behind any of this stuff.
